Description

Technical Field

[0001] The present invention relates to the technical field of seamless gas cylinder detection, and in particular to an intelligent water pressure detection device and method based on seamless gas cylinder production. Background Art

[0002] A seamless gas cylinder is a special pressure vessel used to store high-pressure gas. Its core feature is that the cylinder is made of a whole section of seamless steel pipe without welding seams, which gives it a significant advantage in pressure resistance.

[0003] Although seamless gas cylinders have no welds, they may contain microscopic defects in the material or cracks caused during processing. These defects can become stress concentration points under high pressure, causing the cylinder to rupture. Therefore, pressure testing of structural strength is performed to ensure that they meet safety standards throughout their life cycle.

[0004] A portable gas cylinder strength detection device disclosed in the patent application with reference publication number CN118347883B, which drives the inner teeth to engage with the fixed gear ring by the reciprocating screw revolving around the center of the sun gear, thereby driving the reciprocating screw to rotate while reciprocating around the center of the sun gear, and then driving the sliding sleeve to reciprocate up and down along the reciprocating screw, driving the collision part to move accordingly, so as to collide with the rotating gas cylinder at various angles and height positions, so as to simulate the randomness of the collision suffered by the gas cylinder during transportation or use, and ensure all-round detection of the gas cylinder surface. The above-mentioned gas cylinder strength detection device in the prior art has the following defects in actual use: 1) Existing gas cylinders often experience the combined effects of multiple complex conditions during actual use or transportation, including high and low temperatures and turbulence. However, most current gas cylinder testing devices only test the cylinders under static pressure at room temperature or undergo turbulence and collision testing. This results in relatively limited test conditions and fails to truly simulate the actual operating environment of the gas cylinders. As a result, the final test results are difficult to reflect the cylinders' true pressure resistance, which can easily lead to misjudgment of the cylinders' pressure resistance by testers, reducing the credibility of the test results. 2) Currently, when testing gas cylinders for multiple influencing factors, the pressure resistance test for the next test condition can only be carried out after the test for one test condition is completed. During this period, the gas cylinders need to be disassembled and assembled, which not only increases the testing operation, but also makes it impossible to simultaneously apply multiple factors affecting the pressure resistance of the gas cylinder to the gas cylinder being tested, thereby reducing the test effect of the gas cylinder.

[0005] Therefore, the present invention proposes an intelligent water pressure detection device and method based on seamless gas cylinder production to solve the above problems. Summary of the Invention

[0006] In response to the deficiencies in the prior art, the present invention provides an intelligent water pressure detection device and method based on the production of seamless gas cylinders, which solves the problem that existing gas cylinders are often affected by complex conditions such as high temperature, low temperature, and bumps during actual use or transportation. However, current gas cylinder testing devices are mostly only for static pressure resistance or bumpy collision tests at room temperature. The test conditions are single and cannot truly simulate the actual environment, resulting in test results that are difficult to reflect the actual pressure resistance, which can easily cause misjudgment by testers and reduce credibility. In addition, when conducting multi-condition testing, the gas cylinder needs to be disassembled and assembled after completing one test condition before the next condition test can be carried out. This not only increases operations, but also cannot apply multiple influencing factors at the same time, thereby reducing the test effect.

[0015] The present invention also discloses a detection method based on seamless gas cylinder production, which comprises the following steps: Step 1: First, place the seamless gas cylinder to be tested in the gas cylinder clamping assembly at a relative position. The gas cylinder clamping assembly is subjected to the gravity of the seamless gas cylinder to form a certain amount of pre-clamping force, and the seamless gas cylinder is stably clamped; Step 2: The intelligent console controls the carrying cylinder to drive the first and second arc blocks to reciprocate at a low speed at a first preset angle, so that the seamless gas cylinders on both sides move in two closed detection spaces respectively. External clean water is delivered to the seamless gas cylinders through the booster pump and the water supply assembly. After the preset amount of clean water is delivered, the booster pump is turned off. As the pressure on the top of the gas cylinder clamping assembly increases, the clamping force on the seamless gas cylinder increases. Step 3: During the reciprocating motion of the seamless gas cylinder, the water pressure inside it is in a dynamic state of change. At the same time, the pressure on the top of the gas cylinder clamping assembly changes synchronously with the gravity of the seamless gas cylinder, pushing or pulling the gas cylinder up or down to simulate the bumpy state of the seamless gas cylinder; Step 4: The intelligent console controls the supporting tube to rotate 180 degrees based on the original state. The two gas cylinder clamping assemblies exchange positions with each other and repeat the test state of step 3. After the detection time is over, the intelligent console controls the gas cylinder clamping assembly to rotate to a position opposite to the material removal port, and the seamless gas cylinder that has completed the inspection can be taken out.

[0016] The present invention provides an intelligent water pressure detection device and method based on seamless gas cylinder production. Compared with the existing technology, it has the following advantages: 1. An intelligent water pressure detection device and method based on the production of seamless gas cylinders, by arranging a first arc sleeve, a second arc sleeve, a first arc block, a second arc block and a supporting tube, can form a relatively closed low-temperature test space and a high-temperature test space in the first arc sleeve and the second arc sleeve during the detection process of the seamless gas cylinder, thereby simulating the low-temperature and high-temperature conditions in the actual use environment for the testing process of the seamless gas cylinder, so that the bottle body material of the seamless gas cylinder can be tested at the actual ambient temperature, thereby improving the reliability of the test results; secondly, the first arc block and the second arc block can swing back and forth in the low-temperature test space and the high-temperature test space, thereby realizing the disturbance of the airflow in the low-temperature test space and the high-temperature test space, ensuring that the temperature at each position in the test space is in a relatively uniform state, ensuring that the bottle body temperature of the seamless gas cylinder is in a relatively stable state, which is conducive to the smooth progress of the testing process.

[0017] 2. An intelligent water pressure detection device and method based on the production of seamless gas cylinders, which drives the supporting cylinder to rotate intermittently through a servo motor. On the one hand, it can realize the disturbance of the airflow in the low-temperature test space and the high-temperature test space by the first arc block and the second arc block. Moreover, after the seamless gas cylinder completes the test in the low-temperature environment or the high-temperature environment, the two gas cylinder clamping assemblies can exchange positions with each other, that is, the seamless gas cylinder that completes the pressure test in the low-temperature test space can enter the high-temperature test environment for retesting, thereby detecting the pressure resistance of the seamless gas cylinder in an environment with a large temperature difference. It realizes that based on providing low-temperature and high-temperature test environments, a different test environment is provided, which truly simulates the various usage scenario temperatures of seamless gas cylinders in real environments, making the pressure test data of seamless gas cylinders richer and further improving the credibility of the test results of seamless gas cylinders.

[0018] 3. An intelligent water pressure detection device and method based on the production of seamless gas cylinders. By arranging a pressure-regulating drive component and a pressure compensation component in the water supply component, the water supply component can not only transport clean water to the seamless gas cylinder through the L-shaped branch pipe, but also transport clean water to the pressure compensation component. During the reciprocating swing of the gas cylinder clamping component, the roller squeezes the clean water stored inside the gas into the seamless gas cylinder when it is acted upon by the arc-shaped protrusion, further increasing the water pressure in the seamless gas cylinder. When the roller enters the arc-shaped groove, part of the clean water in the seamless gas cylinder can return to the pressure compensation component again, thereby realizing the dynamic change of pressure in the seamless gas cylinder, so as to simulate the instantaneous impact pressure effect on the bottle body caused by the liquid inside the seamless gas cylinder flowing in a single direction due to shaking during transportation. Secondly, the pressure compensation assembly can also form a linkage with the gas cylinder clamping assembly. When the water amount in the gas cylinder increases, the pressure on the top of the gas cylinder clamping assembly increases, and the gas cylinder can overcome the friction of the clamping and continue to push the lifting tray down. When the water amount in the seamless gas cylinder decreases, the lifting tray can push the seamless gas cylinder up. Combined with the relative sealed sliding design of the height adjustment branch pipe and the L-shaped water supply branch pipe, the seamless gas cylinder can move back and forth up and down, thereby simulating the bumpy state of the gas cylinder during transportation, so that the seamless gas cylinder can complete the pressure resistance test under various test environments during the automated testing process.

[0027] In this embodiment, the first and second water delivery assemblies 4145 and 4146 have identical structures. The second water delivery assembly 4146 comprises an L-shaped water supply branch pipe a1 fixedly connected to the outer wall of the annular sleeve 4144. A height adjustment tube a2 is sealed and slidably mounted at the bottom end of the L-shaped water supply branch pipe a1.

[0029] The present invention also provides a detection method based on the production of seamless gas cylinders, the method comprising the following steps: Step 1: First, place the seamless gas cylinder to be tested in the gas cylinder clamping assembly 412 at a relative position. The gas cylinder clamping assembly 412 is subjected to the gravity of the seamless gas cylinder to form a certain amount of pre-clamping force, and the seamless gas cylinder is stably clamped; Step 2: Control the carrier cylinder 47 through the intelligent control console 1 to drive the first arc block 48 and the second arc block 49 to reciprocate at a low speed at a first preset angle, so that the seamless gas cylinders on both sides move in two closed detection spaces respectively. External clean water is delivered to the seamless gas cylinders through the booster pump and the water supply component 414. After the preset amount of clean water is delivered, the booster pump is turned off. After the pressure on the top of the gas cylinder clamping component 412 increases, the clamping force on the seamless gas cylinder is increased. Step 3: During the reciprocating motion of the seamless gas cylinder, the water pressure inside it is in a dynamic changing state. At the same time, the pressure on the top of the gas cylinder clamping assembly 412 is synchronized with the gravity change of the seamless gas cylinder, pushing or pulling the gas cylinder upward or downward to simulate the bumpy state of the seamless gas cylinder; Step 4. The intelligent control console 1 controls the supporting cylinder 47 to rotate 180 degrees based on the original state. The two gas cylinder clamping assemblies 412 exchange positions with each other, and repeat the test state of step 3. After the detection time is over, the intelligent control console 1 controls the gas cylinder clamping assembly 412 to rotate to a position opposite to the material removal port 45, and the seamless gas cylinder that has completed the inspection can be taken out.

[0030] The specific process is: the servo motor 413 is controlled by the intelligent control console 1 to rotate to a preset angle of one, so that one of the gas cylinder clamping assemblies 412 is rotated to be opposite to the front material collection port 45, and then the seamless gas cylinder to be tested is placed in the top middle position of the lifting tray 4122. The top of the lifting tray 4122 moves down due to the gravity of the seamless gas cylinder, and the hydraulic oil between the lifting tray 4122 and the inner cavity of the gas cylinder 4121 is squeezed and enters the clamping sleeve 4125 at the corresponding position through the high-pressure hose 4127 at multiple positions. The hydraulic oil in the clamping sleeve 4125 drags the clamping block 4126 toward the seamless gas cylinder, and finally clings to the outer wall of the seamless gas cylinder to clamp the outer wall of the seamless gas cylinder, and then adjusts the gas cylinder connecting nozzle a3 up or down to the appropriate height, and seals and locks the gas cylinder connecting nozzle a3 and the seamless gas cylinder bottle mouth at the corresponding position.

[0031] Then, the servo motor 413 is controlled by the intelligent control console 1 to rotate to the preset angle 2, so that the gas cylinder clamping assemblies 412 at the two positions are rotated to the initial positions, that is, the two gas cylinder clamping assemblies 412 are respectively located in the middle position of the low-temperature test space and the high-temperature test space, and the material taking ports 45 at the two positions are respectively blocked by the first arc block 48 and the second arc block 49. At this time, the low-temperature test space and the high-temperature test space are both in a relatively independent and closed state.

[0032] Then, the refrigeration component 43 and the heating component 44 that have been turned on in advance cool and heat the low-temperature test space and the high-temperature test space respectively, and the test temperatures in the low-temperature test space and the high-temperature test space are controlled within the test temperature range through the intelligent control console 1. The intelligent control console 1 controls the servo motor 413 to drive the two gas cylinder clamping components 412 to reciprocate in the low-temperature test space and the high-temperature test space respectively at a first preset angle value, and the rollers a54 in the first water delivery components 4145 and the second water delivery components 4146 on both sides are in the arc groove b3 and the arc groove b4. The protrusions b2 reciprocate between them. When the roller a54 climbs from the arc groove b3 to the arc protrusion b2, the push rod a53 pushes the piston a52 to move in the cylinder a51 toward the water pressure regulating pipe a56. Part of the clean water in the cylinder a51 is squeezed into the seamless gas cylinder by the piston a52 through the water pressure regulating pipe a56 and the L-shaped water supply branch pipe a1, so that the water volume and water pressure in the seamless gas cylinder increase. After the water pressure in the seamless gas cylinder increases, the preset test pressure is further increased on the basis of the basic test water pressure. After the water volume in the seamless gas cylinder increases, the top of the lifting tray 4122 As the pressure increases, the lifting tray 4122 is pushed further downward, and the rubber blocks at the ends of the clamping blocks 4126 at multiple positions are squeezed and elastically deformed, further increasing the clamping force on the seamless gas cylinder; conversely, when the roller a54 slides from the arc-shaped protrusion b2 to the arc-shaped groove b3, the push rod a53 pulls the piston a52 to move in the cylinder a51 toward the column b1, and part of the clean water in the seamless gas cylinder is sucked into the cylinder a51 by the piston a52 through the water pressure regulating pipe a56 and the L-shaped water supply branch pipe a1, so that the water volume and water pressure in the seamless gas cylinder are reduced, and there is no After the water pressure in the seamless gas cylinder is reduced, the preset test pressure is further reduced on the basis of the basic test water pressure. After the water volume in the seamless gas cylinder is reduced, the pressure on the top of the lifting tray 4122 is reduced, and the lifting tray 4122 is pushed upward. The elastic deformation of the rubber blocks at the ends of the clamping blocks 4126 at multiple positions is reduced, and the clamping force on the seamless gas cylinder is reduced. The seamless gas cylinder moves up and down under the upward or downward reciprocating pushing force of the lifting tray 4122 to simulate the shaking state in a bumpy state and the impact of the clean water in the seamless gas cylinder on the bottle body in the shaking state.

[0033] Next, the servo motor 413 is controlled by the intelligent console 1 to rotate one hundred and eighty degrees, and the two gas cylinder clamping assemblies 412 alternate positions with each other. The seamless gas cylinders that have been tested in the low-temperature test space are transferred to the high-temperature test space for further testing. Similarly, the seamless gas cylinders that have been tested in the high-temperature test space are transferred to the low-temperature test space for further testing. The test operation process on both sides is the same and will not be repeated here.

[0034] After the test, the servo motor 413 is controlled by the intelligent control console 1 to rotate to a preset angle of three, so that one of the gas cylinder clamping components 412 is rotated to a position opposite to the front material removal port 45. At this position, a pressure relief groove with a depth greater than the depth of the arc groove b3 is opened on the outer wall of the pressure regulating drive component 4143. When the roller a54 enters the pressure relief groove, part of the clean water in the seamless gas cylinder enters the cylinder a51, completing the pressure relief of the seamless gas cylinder. Then the test seamless gas cylinder is manually removed, and the bottle status of the gas cylinder is checked to determine whether the gas cylinder is in good condition. If it is good, it will continue to be used, otherwise it will be scrapped.
